TIMBERSEAT.

SPECIFICATION forming part of Letters Patent No. 631,194, dated August 15, 1899.

Application filed Tune 10, 1898. Serial No. 688,050 (No model.)

To all when?, it may concern.'-

Beit known that I, CHARLES BALDERsToN, of Philadelphia, in the county of Philadelphia and State of Pennsylvania,have invented certain new and useful Improvements in rlimber-Seats, of which the followingis a specification, reference being had to the accompanying drawings and to the numerals of reference marked thereon.

My invention relates to improvements in timber caps or seats and girder-supports used to support the vertical posts and horizontal girders in the construction of buildings, and has for its object to provide a device which not only supports the timbers or metal beams, but forms practically a lock for their meeting ends. Devices of this character as heretofore constructed have been made of castiron and do not possess the requisite strength, particularly for use in buildings of great height, where the load to be supported by the structure timbers is very heavy.

My invention has for its primary object the utilization of sections of I-beams having outwardly-beveled flanges for timber-seats,there by making a lighter cap than heretofore made, possessing an excess of strength Vover all rcquirements, and providing a Wedge-shaped seat for the timbers of the structure in which the device is used.

The invention consists of a timber cap Vor seat and girder-support comprisinga section of standard steel I-beam, having outwardlybeveled flanges of such size as may be re-v quired, cut to the proper length and having riveted to the under side two angle-plates sufficiently far apart to allow the upper end of the vertical post or timber on which the cap is to rest to iit snugly between the lower beveled flanges of the I-beam and the angleplates, the said flanges and angle-plates forming a Wedge-shaped socket therefor. The upper side of the I-be'am is provided near each end with a transverse rib riveted thereon, and these ribs form anchors to hold in place the horizontal beams or girders, the ends of which are notched to fit over the ribs.

lIn the accompanying drawings, Figurel is a perspective View of my timber-cap and support as it appears in position, resting on an upright post and supporting the horizontal lbeams or girders and an upper upright post.

Fig. 2 is ahorizontal section of the device. Fig. 3 is a transverse section.

Referring to the drawings, in which corresponding ligures of reference designate corresponding parts, l indicates the timber cap or seat and girder-support proper, the upper and lower beveled iianges 2 and 3, respectively, of Which form side Walls for maintaining the timbers of a buildingin position and being joined by the intervening Web portion la. This part of the timber-seat is made of a section of steel I-beam having outwardlybeveled flanges of rolled steel, the dimensions of which will depend on the .requirements necessary-that is, the size of the vertical posts and horizontal beams or girders and the weight of the building to be sustained. Riveted to the under side of the plate l and a suitable distance apart are two an gle-plates 4. These are also made of rolled steel, so as to possess the necessary strength and form with the outwardly-beveled flanges 8 on the under side of the plate 1 a Wedge-shaped socket for the reception of the upper end `of a vertical pillar or beam 5.

Riveted near each end of the upper side of the plate 1 is a transverse rib or anchor 6, and these ribs are adapted to receive the notched ends of the horizontal beams or girders 7 ofthe building. The adjacent ends of the girders 7 are cut square and also form With the beveled iianges 2 at the upper side of the plate l a wedged-shaped socket for the reception of the vertical beam 8.

If desired, the ends of the vertical beams may be beveled on the sides contiguous to the beveled fianges of the timber-seat; but this is not necessary, as the Weight of the timbers will force them into the Wedge-shaped sockets.

It will be seen that the device herein described is simple in construction, and being made of rolled steel possesses the strength necessary in buildings of great height, and the timbers being seated in the wedge-shaped sockets they will be securely held in position.

Having described my invention, I claiml. Acombined cap and girder-support,com posed of the outwardly-bevelved hanged sides 2, 2, and the intervening flat web portion l,

stantially as shown and for the purpose de- 1o scribed.

In testimony whereof I hereunto set my hand and seal this 7th day of June, 1898.
